   I’m on relatively clean town water, so I replace these every 2-3 years. Best value for drinking water going – comes to about 10-15 cents per day. Removes fluoride and chlorine along with whatever I don’t know about. I cut open an old stage 3 RO filter to see how bad it looked, and it is pretty grungy.

   Better than the undersink systems in my opinion, because you can keep a dispenser jar full and never wait for slow spigot times.

   This is the best RO system I have tried. When I purchased the filter pack had a snag with one filter (my fault) and the company responded quickly , hung in there with me, and solved the problem. After being with out the RO water to make my tea and coffee for a few days the difference was stark and will stick with this system.

   The directions do not indicate that the ro membrane housing would be EXTREMELY difficult to open and necessitate additional tools that are not readily available. Have to make an extra trip to the store to buy a large expensive tool…defeats the purpose of a budget countertop system…

   Makes my water so clean! This is a reliable and high-quality product that delivers excellent water filtration! It’s easy to install and works efficiently, providing clean and great-tasting water right from the tap. The filter effectively removes impurities, and I’ve noticed a significant improvement in the clarity and taste of my water since using it. The build quality is solid

   I got these filters for my APEC countertop reverse osmosis water filter. We rent so this is the best water filter for our needs. These filters work as they should. Just make sure you secure them well and you shouldn’t have any leaks. I was getting water from the tap at 220 ppm unfiltered and about 5-12 ppm filtered with this.

   Extremely pleased with Apec performance. They’ve lasted longer than I expected. Only advice for the company is the when you need technical information. I tried to get info on adapter sizes and which of their own to purchase to adapt to my standard hose faucet connector. Also wanted a pump recommendation from their own supplies. That was a less than helpful experience overall. Nice people. Quality products, but I ended up needing to answer the questions on my own by researching which was difficult for such specific products. But the quality and long lasting nature of their products still made for worthwhile purchases.

   We really do not know if it’s worth the money, or if it is really improving the quality of our water.
   But, we know it is not cheap!

   Second time we replaced filters we discovered the waste water faucet outlet was clogged with mineral deposits. That means the filtration system was doing a good job. It took 3 years to get so clogged that it impeded performance (waste water mixing with filtered water). Other than that maintenance issue, this is an outstanding system.

   Purchase this to remove arsenic from well water. Works as advertised.
